Transfer

Lists in-progress and recently completed data transfers between configured data sources. Read-only. Driven by the data-transfer module.

Use it to monitor a running transfer (row counts, current table) and to confirm a completed run.

Columns

Id - transfer identifier.
Source - originating datasource name.
Target - destination datasource name.
Tables - table list (or pattern) being transferred.
Rows - rows copied so far / total when known.
State - RUNNING, COMPLETED, FAILED, CANCELLED.
Started / Finished - timestamps.

Lifecycle

Transfers are initiated from the Data Transfer page (or programmatically via the data-transfer REST endpoint).
Each transfer registers callbacks on a DataTransferCallbackHandler; this view subscribes and renders progress.
Completed transfers stay in the list until the JVM restarts (no persistence).
